Netflix acquired the exclusive global streaming rights for the series in December 2017 and re-cut the series into 22 episodes of around 50 minutes length. Cliffhangers and scenes had to be divided and moved to other episodes, but this proved less drastic than expected because of the series' perpetual plot twists. Netflix dubbed the series and renamed it Money Heist for distribution in the English-speaking world, releasing the first part on 20 December 2017 and the second part on 6 April 2018. Pina assessed the viewer experience on Antena 3 versus Netflix as "very different", although the essence of the series remained the same. Pina and Sonia Martínez of Antena 3 would later say that the series, with its high demand of viewer attention, unknowingly followed the video-on-demand format from the beginning.

The concepts of familiarity between two persons is expressed through the use of different verbal forms (tu and vous in French, tu and usted in Spanish). It is difficult to transfer the same formal social distance in English, yet this distance is socially extremely important in Latin countries. These type of difficulties make good translation from Spanish (or French) to English (and vice-versa) a daunting task. Pity the translators.
